CEMENTING-MAGHINE.

Application filed May 23, 1914. Serial No. 840,595.

To all whom it mag concern:

Be it known that I, HiRAM HOLDEN, citizen of the United States, residing at Man chester, New Hampshire, have invented certain new and useful Improvements in Ge menting-Machines, of which the following is a specification.

The present invention relates to machines for applying cement or other coating material to stock, and more particularly to machines for applying cement to the uppers of boots and shoes.

a The object of the present invention consists in providing a device adapted to be used .on cementing machines of the class above referred to, which 'will prevent the dissipation of waste cement that escapes during the cementing operation and would otherwise be thrown out on to the Working parts of the machine or be smeared in strings on the stock itself. 1

The invention consists primarily 1n providing a member rotating in opposite di rection to the cement roll and so arranged in relation thereto as to direct practically all the waste cement back into the reservoir.

The invention further contemplates the provision of certain guard plates or shields for protecting the adjacent parts of'the machine from becoming clogged or soiled by the waste cement which runs off of the cement roll.

With this and other objects in view the invention consists in the arrangement and combination of parts more fully set forth in, the specification illustrated in the accome panying drawings and pointed out in the appended claims.

In the drawings, Figure 1 is an end elevation of a cementing machine with one embodiment of the present invention applied thereto. Fig. 2 is a plan view showing the invention in place on the cementing machine. Fig. 3 is a side elevation of the complete'machine. Fig. 4 is an enlarged detail of the cement returning shaft showing the manner in which it is mounted on the machine. Fig. 5 is a detail elevation of the combined journal bracket and gear shield.

Referring to the drawings, the cementing machine is provided with a main shaft 1, having a pulley 2 at one end adapted to be coupled with any suitable power source. Shaft 1 is suitably mounted inbearings in the frame of the machine with one end pro- Specification of Letters Patent.

jecting into a cement reservoir tank secured to the end of the machine. A cementing wheel 5 is rigidly carried on the shaft and is adapted to be normally partly submerged in the cementing fluid contained in the reservoir with its upper periphery extending above the surface of the work table 6. Two upright bracket arms 7, 7, extend vertically from the upper casing of the machine, forming supports and bearings for the operating mechanism of the upper pressure roll 6 The cement returning device which forms the salient feature of the present invention consists of a horizontal metal shaft 8, carried in a bracket plate 9, and so arranged as to have its axis disposed parallel to the main shaft 1. A gear wheel 10 is rigidly fastened on the shaft. 1, near the cement reservoir and meshes with a corresponding gear 11, keyed on the cement returning shaft 8. It will be seen that by this arrangement if the cementing wheel 5 is driven bythe shaft 1 in an anti-clockwise direction the cement returning shaft 8 will be driven in opposite or clockwise direction. The cement returning shaft 8 is so positionedthat its free end is disposed in close proximity to the periphery of the cement ing wheel 5 and is located near its. rear edge. The shaft is formed with an inwardly inclined beveled flange 8 at its extreme outer edge adapted to extend slightly beyond the outer edge of the cementing. wheel 5. beveled flange 8 is formed at a distance from the end of the shaft slightly greater than the width of the cementing wheel 5. Centrally located between the flanges 8 and 8 a third straight sided annular flange 8 is formed on the shaft 8 which is in line with the center of the wheel 5. The bracket plate 9, in which the cement returning shaft 8 is carried, is of such design as to serve the double purpose of forming a double bearing for the work and at the same time forming a shield over the gears 10 and 11.

Referring particularly to Figs. 2 and 5 it will be seen that the bracket 9 is secured in place against the inner vertical side of the work table 6, and is fastened by means of screws 13 passing through a rearwardly extending portion 9 to the upright 7. The bracket plate 9 is practically a solid casting curved along its under side to conform to the contour of the cap casing plate 15, upon A similarly formed inwardly I tend through the solid portions of the bracket to the bearing 16 and 16". through which oil can be supplied as needed. A coiled wire 18 is wrapped-around the shaft 8 and extends from the inner flange 8" above referred to as the enlarged sleeve part 8.

One end of this wire rests on the surface of the work table 6 while the opposite end is bent to extend directly over the cement reservoir in which the wheel 5 is mounted. The wire 18 is maintained against rotation and acts as a conveyer for returning any cement that would otherwise escape, and run along the shaft 8 upon which it is carried. A further guard plate or shield 20 is attached by screws to the side of the work table near the outer edge of the Wheel 5. This shield is formed of hard thin metal which will not easily bend and acts not only as a rigid guide plate for the work butfurl. ther serves to prevent the waste cement from rectly to the cement reservoir.

escaping and running over the end of the machine.

f It will be seen from the above description that when the machine is in operation the cement returning shaft S'rotates in an opposite direction to the cementing wheel 5 and is located in such relative position thereto as to intercept the waste cement that would ordinarily be thrown off, returning it di- The'provision of the wire coil 18 prevents this shaft from further spreading the cement and the plates 9 and 20 give further protection to the exposed parts of the machine and the work or stock as it is fed in.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, 7

' Having described my invention what I claim is e 1. A cement applying machine comprising in combination a cement reservoir, va cementing wheel rotating in one direction, a small cylindrical member rotating in the opposite direction and located in proximity to the periphery of the cementing wheel for returning the cementto the reservoir, and stationary means surrounding said member for returning the waste cement to said reservoir, substantially as described.

2. A cement applying machine comprising a,

in combination, a reservoir, a cementing wheel rotating in one direction, a cement returning member rotating in the opposite direction and comprising a horizontally disposed cylindrical shaft having a pair of inwardly inclined beveled flanges one arranged opposite either edge of the cementing wheel, and a central intermediate annular flange between said beveled end flanges, substantially as described.

3. A cement applying machine comprising in combination, a reservoir, a cementing wheel rotating in one direction, a cement returning member rotating in the opposite direction and comprising a cylindrical shaft having suitableflanges formed thereon and mounted with its'axis parallel to the axis of the cementing wheel, a coiled wire member surrounding a portion of said cement returning member and held against rotation, said member adapted to direct any waste cement, escapingtoward the cementing wheel, substantially as described, I a
